Title: Arteriosclerosis evaluation apparatus
Inventor: NARIMATSU KIYOYUKI
IPC: A61B5/02
Filed: 2001-12-13
Abstract: PROBLEM TO BE SOLVED: To provide an arteriosclerosis evaluation apparatus capable of performing diagnosis on arteriosclerosis with high accuracy. SOLUTION: A simultaneous display means 84 displays a mark on coordinates determined by measured pulse wave velocity PWV and AI (Augmentation Index) on a two-dimensional graph consisting of the pulse wave velocity component and the AI component. Because the pulse wave velocity PWV and the AI both reflect arteriosclerosis, diagnosis on arteriosclerosis based on the pulse wave velocity PWV and the AI can be easily made using the position of the mark displayed on the two-dimensional graph. Thus, for example, even if one cannot easily determine whether there is the need for treatment by medication when only the pulse wave velocity PWV is available, the AI as a value indicating the need for treatment enables one to determin the need for treatment, enhancing th e accuracy of diagnosis.

Title: Switching power supply
Inventor: TAKESHIMA YOSHIHIRO
IPC: H02M3/28
Filed: 2001-12-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide a switching power supply that reduces the secondary current of a transformer during a commutation period in a rectifying part for the output of the transformer, and that cuts conduction loss caused by it.  <P>SOLUTION: In the switching power supply 10, a second rectifying part 5 includes a snubber 8D parallel to a reflux diode 5d. When the commutation starts in a first rectifying part 4, a snubber capacitor 8Dc discharges in the second rectifying part 5. Its discharging current is large enough because it passes through a snubber diode 8Dd and bypasses a snubber resistor 8Dr. The discharging current causes a sufficiently large current Id to flow in the second rectifying part 5 during whole commutation period in the first rectifying part 4. Because an output current I6 from a smoothing part 6 for an external load OL is virtually constant, the secondary currents Ib and Ic of a transformer 3 are reduced sufficiently during the commutation period in the first rectifying part 4.  <P>COPYRIGHT: (C)2003,JPO
